Switch from amd to intel motherboard now have no power


No. Power-supplies are compatible with both Intel and non-Intel motherboards. Look near the Intel CPU for a 4-pin "power" connector -- if there is one, connect the cable from the power-supply into that socket.

Hp pavilion a450n turns on but wont open past countdown


probably itz either minor case of software corruption/improper ground/cpu fan..
or major case of faulty or defective main board/ram/daughter or addon card(s)..

..plz do check the following as in order:..
the Hardware part:..
1)see if the ram(s) is loose/faulty..open clean/remove carbon & or oxide formed on the teeth with an eraser n resit it..or replace with a standby n see..

2) 4) a) see if ur hdd is noisy or emitting any 'ticking' noise (like 'tuk tuk' or 'kirr kirr')..
b) or if the system is not supporting either the newly installed device or itz software/driver /firmware
if so, u need either a fresh os installation or ur hdd is likely to b replaced..

3)remove/clean dust neatly..dust is non-uniform in nature n may cause jam/short circuitry/excess resistance n many more..resulting an increase in heat..

4) open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink Compound" (available in local electronics chip level spare market) between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it tightly in position..

5) on main/mother board..see with a debug card for mb error..may b short..look for defective capacitors(esp above1000mfd)/mosfets..go through the mb's south bridge n the circuit lie around atx connector..the crystal clock generator (if cpu isn't heating up)..

6) [in case of desktop] the smps itself may b defective/faulty..check the outputs of smps viz. 0v (black~ground); +12v (yellow); +5v (red, green~ps-on, violet~pg & grey~sb); -12v (blue); -5v(white); +3.3v(orange)..the 'oscillator and error amplifier ic', or pwm switching regulator circuit..look for defective protector-transformer/resistance(esp 4.7k)/mosfet..
check the battery [both main power & cmos], in case of laptops..

the Software part:..
1) hv a licensed and UPDATED antivirus installed (i prefer avg/kaspersky, remember, without updation a full version antivirus is useless)..

2) download, install n run microsoft kb890830..http://www.microsoft.com/downloads/details.aspx?FamilyId=AD724AE0-E72D-4F54-9AB3-75B8EB148356&displaylang=en..

3) download n run Startup Control Panel..http://download.cnet.com/Startup-Control-Panel/3000-2094_4-10039330.html..'remove all the unnecessary startup items from here..(if u can't find what to remove, post me/us in ur comment with all the items listed in each n every tabs herein)..

4) remove all unnecessary software from add/remove programs..

5) download, install n run 'Advanced System Care Pro'..http://download.cnet.com/Advanced-SystemCare-Pro/3000-2086_4-10399324.html..

6)disable the following:..
a) 'Automatically Restart' right click on my computer->properties->advanced->startup n recovery->(uncheck on the) Automatically Restart;
b)'Error Reporting' right click on my computer->properties->advanced->error reporting->disable error reporting->(uncheck on the) 'but notify me when critical error occur'..

7) Increase the size of Virtual Memory, Initial: 1440; Maximum: 2880

if u r bot a professional, always better to seek advise from ur system admin/vendor....

I cannot get my computer to start up. I am trying


i guess u r a professional..as u r handling power supplies..
ur point of view has always a priority..

no 'the led on the power supply be bright at first and then go dim after connecting the power cord'..this happens when there's no/incorrect oscillation/frequency due to push-pull failure, incorrect wattage output etc.
well, itz likely to b the power supply causing it..!!..

however, check the following:

1) the smps itself may b defective/faulty..check the outputs of smps viz. 0v (black~ground); +12v (yellow); +5v (red, green~ps-on, violet~pg & grey~sb); -12v (blue); -5v(white); +3.3v(orange)..
the 'oscillator and error amplifier ic', or pwm switching regulator circuit..look for defective protector-transformer/resistance(esp 4.7k)/mosfet..

2) if itz not the smps, then it must b ur main/mother board..see with a debug card for mb error..may b short..look for defective capacitors(esp above 1000mfd)/mosfets..go through the mb's south bridge n the circuit lie around atx connector....

3) remove/clean dust neatly..dust is non-uniform in nature n may cause jam/short circuitry/excess resistance n many more..resulting an increase in heat..

4) open the CPU Heat-Sink with fan out of the socket..put some "Heat Sink Compound" (available in local electronics chip level spare market) between the cpu/processor and the CPU Heat Sink *** fan..resit/fit it tightly in position..

5) see if the ram(s) is loose/faulty..open clean/remove carbon & or oxide formed on the teeth with an eraser n resit it..

6) check cmos battery (above +3v)..

..plz give higher priority to step2 (as listed above) CAREFULLY..

always better to seek advise from ur system admin/vendor....

When the computer is turned on the cpu fan spins up and then stops, restarts all over again. The +5 and +12V on the drive connectors goes from 0 to proper value when fan is spinning. I have disconnected...


gud..!! it seems u may b a professional handling power supplies, if u r not refer to ur system admin/a professional....

however, itz quite common smps problem..guess the 'pg(violet +5v)', 'sb(if present, grey +5v)' n +3.3(orange) signals r fine..the problem probably lies in 'oscillator and error amplifier ic', or pwm switching regulator circuit..look for defective protector-transformer/resistance(esp 4.7k)/mosfet..
replace the smps with a standby n see if rectified..!!

if itz not the smps, then it must b ur main/mother board..see with a debug card for mb error..may b short..look for defective capacitors(esp above 1000mfd)/mosfets..go through the mb's south bridge n the circuit lie around atx connector....

How to find power consumed by instruction for any architecture?


The only thing you can do is read the amperage and wattage with a multimeter and clamp. It would not be possible by any easily reconstructable means to measure such a thing right off the CPU.

Newly installed, first boot up PSU problem


If it's a new PSU, then return it for a replacement...Even online distributors will replace faulty units. And since your old PSU works on it, I'd have to say it's the new PSU that's faulty. Did you make sure that it's the right PSU for the CPU that you have? (As there are PSU units for AMD and seperate ones for Intel...Intel just has a additional power cord to connect to the motherboard)
